amd cpu hardware quirk gimps perf
windows workaround available now

Nothing. It's shit compared to Intel anyway.

Ryzen CPUs are made up of two sections with four cores each. Those four cores can talk to eachother very quickly, faster than a traditional monolithic CPU. The downside is that if they need to talk to cores in the other section there's a larger delay. This update makes the Windows scheduler take this into account, and assign tasks reliant on cross-core communication to the same group of four cores.

Why was this not done already? Why did it take two years? Fuck knows.

1) the windows scheduler (thing that allocates processor resources to programs) will now try to fill cores close to each other with threads (parts of programs) instead of spreading them out as much as possible. this reduces the latency costs of routing over them when the threads need to communicate with each other... but at the downside of an increase in power density

2) modern processors power off some components when not in use (c-states and p-states) to save power and reduce temperature even when the computer is powered on and running but programs aren't very demanding. there is an inevitable delay when turning those components back on. most of this delay comes from the operating system (windows) trying to decide when to send a signal to the processor to turn them on, however on the new ryzen there is a dedicated part of the processor to detect a sudden increase in program activity, and using this turns out to be much faster than letting the operating system figure it out

see for 1)

2) CPPC2 is the technology for reducing clock speed ramp time from ~30ms to ~1-2ms on ryzen processors. AMD claims an improvement of up to 6% performance in certain workloads from this alone.

>two 24 core dies
NOOOOOOOO INTELBROS

How does it feel knowing your 3 year old $1700 HEDT Intel CPU is about to get railed by a $500 mainstream AMD CPU?

pretty sure it'll get destroyed by the $329 8-core if it performs anywhere close to a 9900k

i doubt it'll improve anything if you never go deeper than the halt state and don't use frequency scaling, but it'll be interesting to see when benchmarks come out as you can disable even that on linux i believe

now if only we got this update for windows 7...

ayymd needs to learn how to do CPUs properly, first, instead of the OS having to resort to workarounds.

That's a lot of vulnerabilities you got there.

and what about the loonix? Does it have it implemented already?

indeed, one would think think the sane way to handle it is that the CPU itself sorts how the workload is distributed, instead of being a dumb brick that relies on the OS.
And while we are on this topic, this is also the key to being able to distribute single core tasks into multiple cores without having to rely on programers to fix that.
There is already prototypes for this.

If you think about it, it's really half baked implementation of "MOAR COARS" which are dumb cores that can't into parallel and intelligent work distribution.

>t.legally retarded

is this the shill defense force or something?
you didn't fucking address any of the points and literally went "hurr durr u a retard"
Not an argument and if all you can do is shitpost then fuck off.

linux supports thread grouping depending on what scheduling policies it's configured with

bib.irb.hr/datoteka/743117.CTS_11_2850.pdf

UEFI CPPC2 seems to have an implementation (patchwork.kernel.org/patch/7539651/) and on non-supporting processors you could disable various power saving states with some kernel cmdline parameters

wiki.ntb.ch/infoportal/_media/embedded_systems/ethercat/controlling_processor_c-state_usage_in_linux_v1.1_nov2013.pdf#page=6
>Disabling C-states in this way will typically result in Linux using the C1 state for idle processors, which is fairly fast. If BIOS doesn’t allow C-states to be disabled, C-states can also be limited to C1 with the kernel parameter “idle=halt”
>If a user wants the absolute minimum latency, kernel parameter “idle=poll” can be used to keep the processors in C0 even when they are idle (the processors will run in a loop when idle, constantly checking to see if they are needed). If this kernel parameter is used, it should not be necessary to disable C-states in BIOS (or use the “idle=halt” kernel parameter). Take care when keeping processors in C0, though--this will increase power usage considerably. Also, hyperthreading should probably be disabled, as keeping processors in C0 can interfere with proper operation of logical cores (hyperthreading). (The hyperthreading hardware works best when it knows when the logical processors are idle, and it doesn’t know that if processors are kept busy in a loop when they are not running useful code.)

this is an anonumous imageboard
you seem to have no clue what the fuck youre talking about

>one would think think the sane way to handle it is that the CPU itself sorts how the workload is distributed, instead of being a dumb brick that relies on the OS.
That's effectively the definition of what an operating system does dumbshit. It organizes and feeds data to the CPU to calculate, then organizes the output for user interpretation.

Except, it can't break up a single task itself, there has been prototype solutions that make the CPU break up the workload of even single threads and handle it more effectively.
Just because you are 100% ignorant about the subject doesn't mean you can spout your ignorance as fact and speak for literally whole of humanity.
Read up on the subject for fuck sake.

There would be a couple thousand tweets bitching about Intel delays if he applied the same standards to them.

He's going to kill himself in 3 weeks.

you have no fucking idea how twisted his mind is. he's unironically using AI to block users that argue with him. check this tweets

Optimisation for your hardware on windows.
You ever seen how gentoofags say compiling the kernel specifically for your cpu yields better results? Kind of the same thing.

It's foolish to bias it like this. There was an issue now there's not. Blaming either side for being incompatible doesn't make sense unless we know how this was introduced.

> french
Makes sense

That's not 'twisted'. It's actual shilling. It makes perfect sense to remove any descenting opinion where you have the power.
It may seem silly but remember RTX? Virtually nobody bought it as a feature. Now 'everyone' wants that from Navi cards. How did that happen? People get really excited about playing quake 2 raytraced? Even if that's the case they're not rational consumers. It makes no sense.
If anything I would say RTX proves this kind of push isn't currently a good idea. It will be. Marketing is powerful and can change people's minds.

This is an unseen before level of echochambering yourself and getting delusional

What happened to VISC? Shit just disappeared with no news.

Stupid cunts just need a reason to not buy AMD products. No matter how stupid their reason is.

I get the same benefits by manually assigning core 0, 1, 2, 3 to a program with cpu affinity, right?

Man, this shit is really old. Intel first glued 2 p4 ee to compete with an actual dualcore fx cpu from amd.

>WINDOWS 10 OPTIMIZED FOR "ZEN"
yes. "zen".

He's mentally ill. Like most Intel shills.

before the update the windows sc was issuing a thread at random on random cores wasting resources for nothing

now its issuing threads on each ccx first

recompile your gentoo

Yea, now windows will do the same automatically.

people want to hedge just in case nvidia gets enough developers on board to actually make that shit relevant, and just in case non-raytracing lighting is relegated to backup/afterthought tier
the last time anybody heard about it was back in 2016 when Intel bought it and presumably left it to die

So, LTSC 2019 when?

Hes medically retired for having schizophrenia unironically. Twitter is his entire life now.

>Hes medically retired for having schizophrenia unironically
sauce please? is he actually legitimately mentally ill?

still would date if she's cool

Doubt I could dig it up, the guy has been retired for years, and it was basically insider gossip even then. He was an engineer/technician at intel for the Core series, was actually a big shot in the company. Then he leaves the company very abruptly. At first people were saying he had cancer or something, but some other forumite who worked for intel said he left for a personal medical issue, and apparently it was mental health related. The guy resurfaces eventually and does nothing but rant and sperg out on social media like an actual teenager. Those in the known basically said he got diagnosed and intel politely forced him to retire. He just shills for intel day in and day out now, thats his entire life, not even on company dime.

ryzen keeps getting better and better :)
